When developing new or improving already existing products and systems, it is vital to have good understanding of them. In many cases it can be difficult to force all effects of a new design. Therefore it is important to perform tests and experiments. However this procedure might be both costly and time consuming. MathModelica System Designer is a modeling, analysis, and simulation environment for engineers at companies that design products or systems and need a better understanding of their behavior. With MathModelica System Designer it is possible not only to optimize your tests and experiments, but also to study phenomena that would otherwise be impossible to study and understand. MathModelica System Designer is now independent of other software, giving several advantages, for example, handling, flexibility, and pricing.
